LUBRICATOR.

Specification of Letters Patent.

Patented Nov. 21, 1905.

To all whom 2125 may concern.-

Be it known that we, HENRY HEcK and i/VILLIAM M. SIMMONS, citizens of the United States of America, and residents of the city and county of Albany, State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

Our invention relates to lubricators; and the object of our invention is to provide a device for automatically lubricating a cylinder containing a reciprocating piston and which provides a means for observing the oil which is transmitted from the lubricator to the cylinder, together with such elements and combinations as are hereinafter more particularly set forth. We attain this object by means of the mechanism illustrated in the accompanying drawing, in which the figure is a longitudinal section of the lubricator.

The lubricator is provided with a cylinder A, within which is secured or constructed in tegral therewith a core B, through which core is bored a passage-way C and a similar passageway D, the side of the top of the core B being preferablyflushwith the top of the sides of the cylinder A, but cut out slightlyfrom near the edge of the sides of the end of the core to form a depression, as at E, this for the purpose of makingacommunicationbetweenthepassageway D and the passage-wayCwhen the cover F is screwed onto the sides of the cylinder A and at the same time to prevent communication between the passage-wayD or the passage-wayC with the interior of the cylinder A. This is accomplished by arranging on the cover F a flange], which has screw-threads meshing with similar threads in the upperinterior portion of the sides of the cylinder A, and also ar ranging on the interior of the cover F an annular shoulder G, which engages the edge of the top of the core B.

The passage-way C in the core B communicates by an opening or passage way H through the bottom of the cylinder with the interior of the projection J, formed on or attached to the bottom of the cylinder. For the purpose of enabling one to see the oil discharged through the opening H the opposite sides of the projection J may be cut away, as at K K, and glass placed Within the projection J, covering said openings K K, respectively.

To the projection J we attach a nipple Lby means of screw-threads engaging the threads in the interior surface of the projection. The

nipple L is also provided with screw-threads to engage with the cylinder to which the lubricator may be attached. (Not shown.) Through the nipple L is a passage-way Z, communicating with the opening in the proj ection J.

The core B is provided near the bottom of the cylinder A with a groove M, which communicates with the passage-wayD in the said core.

Through the cover F we place a spindle 0, preferably pointed at the end 0, adapted to engage the flaring opening in the passageway 0 of the passageway H. The pointed end 0 of the spindle is preferably arranged so as to entirely close the opening when it is seated therein.

The spindle O is preferably provided with screw-threads meshing with screw-threads in the cover, through which it passes, whereby the position of the spindle in reference to the opening H may be regulated. We also place on the spindle O a regulating-nut P, which may be arranged to determine the distance which the spindle may be allowed to enter the passage-way C when the head R of the spindle is rotated The operation of our invention is as follows: When a piston is moved in a'cylinder (not shown) so as to compress the air therein, there will be forced through the opening Z, projection K, passage-way H, and passageway C a current of air, which will find its way through the passage-way D into. the oil or other lubricating fluid in the cylinder A and will work its way to the top of the cylinder A. Upon the return movement of the piston in the cylinder, which tends to exhaust the air in the cylinder, there will be a suction exerted, supplemented by the pressure of the air in the top of the cylinder A, which will cause the lubricating fluid to enter the passage-way D and be conveyed therefrom to the passage-way 0, through the projection J and nipple L to the cylinder. Thus at each outward movement of the piston there will be delivered to the cylinder a quantity of oil, depending upon the position of the spindle in reference to the passage-way H in the bottom of the core of the cylinder. The quantity of oil thus delivered may be observed through the sides of the projection J.

What we claim as our invention, and desire to secure by Letters Patent, is

A lubricator consisting of a cylinder; a centrally-disposed core therein, containing a pasin position; an adjustable spindle secured to said cover; with a means for permitting observation of the interior of the said projection, all substantially as described.

HENRY HECK. WILLIAM M, SIMMONS.
